Abstract
A wireless communication apparatus includes: a receiving unit that receives a signal indicating a frequency band having the highest priority of selection among a plurality of frequency bands; and a transmitting unit that transmits data in parallel, using the frequency band having the highest priority of selection and a frequency band having a priority of selection lower than that of the frequency band having the highest priority of selection.

A wireless communication system comprising:
- a first communication apparatus;
- and
- a second communication apparatus, wherein
- the first communication apparatus comprises:
- a first receiving unit configured to and/or programmed to receive wireless signals by a plurality of frequency bands;
- a first information storing unit configured to and/or programmed to store priorities of selection of the plurality of the frequency bands;
- a second information storing unit configured to and/or programmed to store first information, the first information indicating a first frequency band, the first frequency band being included in the plurality of the frequency bands, a priority of selection of the first frequency hand being the highest among the priorities of selection of the plurality of frequency bands, receiving qualities of the plurality of the frequency bands being equal to or greater than a threshold value, the threshold value indicating the lowest receiving quality level;
- a first transmitting unit configured to and/or programmed to transmit the first information stored in the second information storing unit;
- and
- a first communication control unit configured to and/or programmed to control the first receiving unit to receive the wireless signals, the wireless signals being transmitted by the first frequency band and a second frequency band, the second frequency band having a lower priority of selection than that of the first frequency band, the second frequency band being included in the plurality of the frequency bands, and wherein
- the second communication apparatus comprises:
- a second receiving unit configured to and/or programmed to receive the first information transmitted by the first transmitting unit;
- and
- a second transmitting unit configured to and/or programmed to transmit the wireless signals in parallel by the first and second frequency bands, the transmission of the wireless signals being performed based on the first information received by the second receiving unit.
